A calm arithmetic game for ages 6 to 8. Tap the candy with the right answer before it lands. No ads, no purchases, no data collected, and it works offline. Prim Math helps children aged 6 to 8 become fluent at adding and subtracting up to 20, in short sessions of two or three minutes. How it works A question sits at the bottom of the screen. Four candies, each with a number, drift down. The child taps the one that is the right answer. Made for children • No losing and no overall timer: every level can always be finished • Questions that were missed come back once more at the end of the level • Pick a topic: addition, subtraction or both. Each has its own levels, 16 in all, from numbers up to 5 through to 20 • Up to 3 stars per level, and any level can be replayed for more • Each topic has its own scenery and treats: candy land, an ice cream beach and a cookie twilight sky • Numbers and icons instead of text, so a child can play without reading instructions • Large tap targets; each candy differs in shape as well as colour Peace of mind for parents • No advertising • No in-app purchases • No account • No data collected or sent anywhere • No links out of the app • Works without an internet connection Progress is saved on the device only.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Pick a topic from the first screen: addition, subtraction or both. Each topic has its own ladder of levels, 16 in all. Stars you already earned carry over. New scenery for each topic: candy land for addition, an ice cream beach for subtraction and a cookie twilight sky for the mixed levels, with new treats to tap. Prim now waves, claps and blinks, correct answers sparkle, and screens change more smoothly.
